@tanmay.01 If you were referring to the GUI for dconf, there shouldn't be an option for session under com > canonical > indicator, although I do not know why. But the show-real-name-on-panel boolean key should definitely work in defining the state of your username in the panel. Please give the commands a try in your terminal, and be sure to reboot. Get back to me! :)
